BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to communication devices, and specifically, to a communication device that integrates wireless and wireline technologies to control information exchange with communication networks.
2. Description of the Prior Art
Wireline communication networks provide various services, such as telephony, email, information content services, and internet access using wireline communication paths. Wireline communication networks provide fixed service to a place. Wireless communication networks provide similar services using wireless communication paths. Wireless communication networks provide mobile service to a person. Wireline communication paths are physically tangible mediums between wireline devices. Examples of wireline communication paths include copper, aluminum, and fiber optic cabling carrying protocols such as Synchronous Optical Network (SONET), Asynchronous Transfer Mode (ATM), Transmission Control Protocol/Internet Protocol (TCP/IP), Ethernet, T1, DS3, and dense wave division multiplex fiber optic lines. Wireless communication paths propagate electromagnetic radiation over an air interface between wireless devices. Examples of wireless communication paths include personal communications service (PCS) links, microwave multipoint distribution service (MMDS), millimeter wave links, code division multiple access (CDMA) links, time division multiple access (TDMA) links, spread spectrum links, and microwave links.
Unfortunately, wireless communication service and wireline communication service are mutually exclusive and independent. As a result, duplication occurs when customers require a similar service for both a wireless device and a wireline device. For example, a customer that requires email service at the office and on a cellular telephone would subscribe to a wireless service and a wireline service. In addition, these multiple services are inconvenient and time consuming to the user and result in increased demands on the providing network during busy periods and peak traffic conditions.
Docking station technology provides one solution to the problem of duplicate services. Docking stations enable wireless devices to be utilized with a wireline service. For example docking stations permit mobile devices such as personal digital assistants (PDA's) and/or PCS handsets to utilize wireline telephone technology to access email and internet services. Nevertheless, docking stations are limited to a fixed environment of use and still require a wireless service to provide mobile communication outside of the docked environment.

FIG. 2 is a flow chart illustrating one example of the operation of the communication device 100 according to the present invention. The operation begins at step 200. At step 201, the processing system 104 communicates with the communication network 106 via the network interface system 102 at user defined time intervals. The time intervals are defined in the user profile setup prior to communication with the communication network 106. If the capacity of the communication network 106 is constrained at step 202, the processing system 104 reduces the information retrieval cycles at step 209. Those skilled in the art will appreciate that there are multiple methods the processing system 104 could use to determine that the capacity of communication network 106 is constrained. Some examples include, receiving a capacity constrained message from the communication network 106 or detection based on access and response times. If the capacity of the communication network 106 is not constrained at step 202, processing proceeds through steps 203-207 as described below until the information is retrieved at step 205 and processing ends at step 210.
Responsive to reducing the number of information retrieval cycles at step 209, the processing system 104 retrieves information from the communication network 106 at the reduced information retrieval rate at step 203. At step 204, the processing system 104 provides retrieved information to one or both of the wireline device 107 and the wireless device 106 via the wireless interface system 101 and the wireline interface system 103. The information is provided according to the information delivery parameters defined in the user profile. If all of the requested information is retrieved from the communication network 106 at step 205, the operation ends at step 210. Otherwise processing proceeds at step 206. If the capacity of the communication network 106 has changed at step 206, processing continues at step 207, otherwise processing continues at step 203. If the constraint has decreased at step 207, the processing system 104 increases the information retrieval cycles at step 208 and continues to retrieve information at step 203 at the increased retrieval rate. If the constraint has increased at step 207, the processing system 104 decreases the information retrievals cycles at step 209 and continues to retrieve information at step 203 at the decreased retrieval rate. Steps 203-207 are repeated until the information is retrieved at step 205 and processing ends at step 210.

Those skilled in the art will also appreciate that wireless interface system 303 could also be a part of docking interface system 302.
The telephone interface system 304 could be a conventional voice interface that acts as a POTS interface, supervises signals, channels voice lines, or resolves contention between voice lines. The telephone interface system 304 could also provide local loop voice functionality including dial tone and wireline feature transparency as well as VoIP technology. In some examples of the present invention, the telephone interface system 304 could function as the network interface for communication device 100 to exchange information retrieval messages and information with the communication network 106.
The computer interface system 305 could be any device or group of devices configured to exchange information with the computer system 308 under the control of processing system 300.

The computer interface system 305 could also act as a POTS interface, supervise signals, channel voice lines, or resolve contention between voice lines. In some examples of the present invention, the computer interface system 305 could also function as the network interface for the communication device 100 to provide network connectivity and exchange information retrieval messages and information with the communication network 106.
The wireline network interface system 309 could be any device or group of devices configured to exchange information with the communication network 106. One example of the wireline network interface system 309 includes without limitation, a metropolitan fiber ring interface system using SONET and/or ATM protocols.

One example of the wireless network interface system 310 includes without limitation, a terrestrial microwave system. The wireline interface system 309 and the wireless interface system 310 could also provide packet transmission network architecture to provide always-connected communication services to processing system 300.
Processing system 300 could be any processing system configured to exchange information with the communication network 106 and provide retrieved information to at least one of the PDA 306, the computer system 308, and the telephone 307. Processing system 300 could use computer interface system 305, the telephone interface system 304, the wireless interface system 303, the wireline network interface system 309, and/or the wireless network interface system 310 for network connectivity and information retrieval.

The information could be any information provided over the communication network 106. Some examples of information include without limitation, content information, data file transfer, video information, audio information, e-mail, world wide web browsing using PUSH or PULL technologies, facsimile communication, audio broadcasts, and video broadcasts.
Operationally, the processing system 300 controls the flow and presentation of the information to the PDA 306, the telephone 307, and the computer system 308 based on instructions defined in the user profile. The user controls the user profile to provide instructions to the processing system 300 that define when, where, what, and how the information is provided to the PDA 306, the telephone 307, and the computer system 308. The user profile could be stored in memory 301 and accessed using computer system 308 and/or processing system 300, or the user profile could be stored on computer system 308.
The following are several examples of the operation of the processing system 300 based on the user profile. Those skilled in the art will appreciate that an exhaustive illustration of all possible operations of the processing system 300 would be impractical. As a result, the present invention is not limited to the specific examples and illustrations discussed below, but only by the claims and their equivalents.
The user profile could be configured to define various time intervals for information retrieval and update. The time intervals could be individually defined for specific types of information. For example, all information could be retrieved at the defined time interval(s) or the information retrieval could be bifurcated such that e-mail information is retrieved hourly while weather reports are retrieved only in the morning, and stock quotes continually updated during the course of the day.
The user profile could also be configured to designate various delivery requirements. For example, email could be delivered to the PDA 306 during mobile operation and to the computer system 308 when the PDA 306 is docked in the docking interface system 302. In another example, email could be delivered to the PDA 306 and a copy delivered to the computer system 308. In yet another example, email could be delivered as described above while weather information and/or file transfer information is only delivered to the computer system 308.
The user profile could also be configured to designate specific delivery formats. For example, retrieved information could be provided to a screen on the designated device e.g. computer system 308 or to a memory in the designated device. Information could also be cached in memory 301 for instant access by one of the PDA 306, the telephone 307, and the computer system 308.
The processing system 300 could also control information delivery in combination with the user profile. For example, where the information to be delivered is too large for the intended delivery device, e.g. the screen on the PDA 306, the processing system 300 could control delivery to provide only portions of the information to the PDA 306 and provide the complete information to another device such as the computer system 308. Similarly, the processing system 300 could reformat the information for delivery to the designated device to accommodate device limitations. For example, a weather map designated for delivery to the PDA 306 could be provided in a text format to the PDA 306 and in graphical format to the computer system 308.
Processing system 300 could also coordinate with synchronization software on the computer system 308 or the PDA 306 to deliver information. For example, processing system 300 could wake up during power down modes, components on computer system 308 necessary for storing and formatting retrieved information. Those skilled in the art will appreciate that the processing system 300 could accommodate various other wireless and wireline devices although only the PDA 306, the telephone 307, and the computer system 308 are shown on FIG. 3 for clarity.
During information retrieval, the processing system 300 dynamically adjusts the information retrieval requests based on the capacity of the communication network 106. FIG. 4 is a flow chart illustrating one example of the dynamic adjustment of the information retrieval based on the capacity of the communication network 106 according to the present invention.
Information Exchange Operation FIG. 4:
On FIG. 4 the operation begins at step 400. At step 401, the user defines the desired information and delivery requirements in the user profile and configures the desktop synchronization software on computer system 308 and/or PDA 306. The user could also specify information categories to be cached in memory 301 for instant access. At step 402, the processing system 300 transmits an information request message to the communication network 106 at the designated information retrieval time defined by the user profile. The communication network 106 processes the information request message and provides a network capacity message to the processing system 300 at step 403. If the network capacity message indicates the capacity is unconstrained, for example network utilization is 40%, processing continues at step 404 and the information is retrieved from the communication network 106 at normal retrieval cycles at step 407.
If the network capacity message indicates the capacity is constrained, processing continues at step 405, and the processing system 300 reduces the information retrieval cycles at step 406 by the amount of capacity constraint. For example, the network capacity message at step 405 could indicate that the communication network 106 utilization is at 90% at step 405. Responsive to the 90% utilization, the processing system 300 reduces the information retrieval cycles by 90% at step 406 and the information is retrieved at step 407 at the reduced retrieval rate.
If during the retrieval of information at step 407 the capacity of the communication network 106 changes, the processing system 300 dynamically adjusts the information retrieval cycles to accommodate the capacity change. For example, if the processing system 300 receives a network capacity message indicating that the network utilization has changed from 40% to 60%, the processing system 300 could reduce the information retrieval cycles during the information retrieval at step 407 by 20%. Alternatively, the processing system 300 could reduce the information retrieval cycles by the full 60%. Similarly, if the processing system 300 receives a network capacity message indicating the network utilization has changed from 90% to 60%, the processing system 300 could increase the information retrieval cycles during the information retrieval at step 407 by 30%. Thus, the processing system 300 continually adjusts the information retrieval based on the amount of network constraint during the information retrieval at step 407. Upon completion of the information retrieval at step 407, the processing ends at step 408.
The above-described processing systems can include instructions that are stored on storage media. The instructions can be retrieved and executed by a processor. Some examples of instructions are software, program code, and firmware. Some examples of storage media are memory devices, tape, disks, integrated circuits, and servers. The instructions are operational when executed by the processor to direct the processor to operate in accord with the invention. The term “processor” refers to a single processing device or a group of inter-operational processing devices. Some examples of processors are integrated circuits and logic circuitry. Those skilled in the art are familiar with instructions, processors, and storage media.
Those skilled in the art will appreciate variations of the above described embodiments that fall within the scope of the invention. As a result, the invention is not limited to the specific examples and illustrations discussed above, but only by the following claims and their equivalents.
